Fig. 3 represents another mannerof securing the rim to the disk or body. t

My invention relates to a belt-pulley; and it consists in making boththe rim and body or disk of a plurality or multiple of veneers; as

more fully described hereinafter.

Referring to the drawings, Arepresents the rim of the pulley, B the bodyor disk, C the hub, and D D plates for securing the disk or body to thehub. The rini is made of a plurality of veneers glued or otherwisesecured together. Any suitable nuniber oi' theselayers may be used, andit would be desirable to have the grain of the wood of the differentlayers run as niuch as possible i1 opposite directions.
